PORTABLE MACHINE FOR REGROOVING RAILWAY-SLEEPERS.

To all whom it may concern:

Be it known that I, ALBERT CoLLEr, a citizen of the Republic of France, residing in Paris, France, have invented certain new and useful Improvements in Portable Machines for Regrooving Railway-Sleepers, of which the following is a specification,

This invention relates to a portable regrooving machine or apparatus which will allow of re-grooving railway sleepers upon the track itself as repairs to the latter become necessary.

This re-grooving machine consists chiefly of a carriage mounted upon four wheels on which rests by means of rollers a transverse support formed of two tied parallel tubes on which are fixed two vertical cutters operated by electric motors, the adjustable distance apart of the axes of the two cutters.

being equal to that of the track. The ad vancement and lowering of the cutters take place by hand and through the medium of a hand-wheel. Perpendicular-1y to the two transverse tubes of the support are arranged manipulating bars, four in number and it is only necessary for four men to raise the support by means of these bars in order to remove the cutters from the track and to afterward withdraw the carriage to render the track completely free. This operation is performed in less than a minute. As shown, owing to this arrangement, a person can work with this re-grooving machine in an almost permanent manner upon the tracks for repairing them without in any way impeding the traffic.

The following to the accompanying drawing will enable the construction and operation of this port- 2 able re-grooving machine to be fully understood.

Figures 1 and 2 are front and side views Fig. 3 shows the traveling carriage on a larger scale in side elevation partly in section. Fig. 4 is a plan of Fig. 3 also partly in section. Fig. 5 is a section showing the arrangement for causing the vertical displacement of the cutters. Fig. 6 is a detailof the mounting of the motors on their tubular supports, which mounting allows the inclination of the cutters with regard to the vertical in cases where the re-groovin g is required robe made with an inclinationof one twentiethfor. the

placing of VighoIes rails.

The regrooving machine consists chiefly of a supporting carriage A which is made to run over the tracks to be repaired and provided with rollers upon whichthe tied tubes supporting the motors and the cutters which they actuate rest and can be moved in a direction parallel to the sleepers. The sup porting carriage A comprises a pair of tubular rods B transverse of the rails and ribbed cheek pieces 6. Between these cheek-pieces 6, upon axles D, are j ournaled wheels E upon which the carriage may be rolled along the track. The axles D are preferably threaded in the ends of the tubular rods B and pass through theends of cheek pieces 5, whereby the axles may be turned in the tubular rods B to adjust the distance between the wheels to the width of the track. The wheels are preferably mounted on ball bearings and the axles D are secured in their adjusted positions in the tubes B by clamping collars a.

Also between the cheeks b and between the I two wheels E, is arranged an axle F parallel with the track supported by a ball bearing d which carries two rollers Gr having deep grooves. On the said rollers G rest two parallel tubes H between the ends of which are fixed at a suitable distance apart, by means of clamping collars or sleeves e, the two vertical electric motors J each carrying and actuating a cutter L. Adjustable stops 0 limit the displacement of the tubes supporting the motors. Each cutter, protected when at rest by a case or frame f arranged at the lower part of each 'motor, can be moved vertically in order to regulate the depth of the groove by means of the-following arrangementz -A hand-wheel M is mounted intermediate the two motors for raising and lowering the cutters into operative position. Thejhand-wheel M is mounted betweentwo cheeks g of collars h which are adapted to be clamped upon the tubes H. Connected to the hand-wheel, preferably through universal joints 2' and telescoping shafts, is a bevel pinion j which gears with another bevel pinion 70 operating a screw Z. The screw [engages with a tube or slide m, constituting a nut to which is fixed another tube at within which is mounted upon ball bearings a sleeve 0 carrying at its lower part the cutter -L. By turning the screw Z, the nut m and the cutter is "caused 'to rise or 'de- "scend. The shaft N of the motor is coning in a groove in the sleeve, thus allowing of the relative longitudinal displacement of the said sleeve with regard to its operating shaft. The different parts above set forth are arranged and move in a casing or frame 0 situated beneath the motor J (see the detail Fig. 5.)

hen it is required to re-groove worn sleepers the re-grooving machine having been previously adjusted to the width of the track on which it is to operate by adjusting the axles D in the tubes 13, and spacing the cutters the desired distance apart, the sleepers are detached from the rails and slide transversely under the track a proper amount to bring the parts of the sleeper which are to be grooved under the cutter. An operator placed at the handwheel M regulates the depth of the groove for both ends of the sleeper simultaneously and the cutters, placed in front of the sleeper at the required spot by the displacement of the tubes H upon the rollers G, are advanced by hand against the sleeper to effect the re-grooving by pushing the carriage A which moves to the required extent over the rails P. If the re-grooving is effected in several strokes as in the example shown by reason of the diameter of the cutters, the carriage A is brought back and again pushed as many times as is necessary, care being taken, however, to laterally displace the motors to a variable degree, according to the width of the groove at each forward and return movement.

As will be observed, the cheeks or longitudinal bearers Z) of the supporting carriage are so curved or bowed that by turning the carriage upside down the rollers G and consequently the height of the support carrying the cutters resting on said rollers, are raised so as to adapt the ma chine for use with sleepers for Vignoles rails, which. sleepers are placed higher with relation to the rails.

If it is necessary to clear the track for any reason, such as for the passage of a train, this work can be performed very rapidly, that is to say, in less than a minute. Four men lay hold of the entire structure consisting of the motors and their coupling tubes by means of manipulating bars Q, arranged on each side of each of the motors and carry it outside the track, while other workmen proceed to remove the carriage. These manipulating bars are preferably placed at the end of the supporting tubes in order not to prevent the rocking of the cutters.

In cases where the re-grooving is to be effected upon sleepers for Vignoles tracks, it is necessary to be able to give the motors the required inclination to the vertical.

For this purpose the motors J, the manipulating bars Q of which are engaged in eyes in the clamping collars a, can be subjected to displacement with the said manipulating bars as an axis. Two notches g r made in the manipulating bars and corresponding, the one to the position of the motor for regrooving upon ordinary tracks, and the other to its position for re-grooving upon Vignoles tracks, serve to maintain each motor in the desired position by the introduction into the proper notch of a screw 8. symmetrically to the screw 8 is arranged another screw 6 not engaging in either of the two notches and simply serving as stoppers for plugging that hole which is left free by the screw 8.

It will be obvious that this machine can serve for making grooves in new sleepers.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. In a machine for grooving railway sleepers, the combination of a carriage adapted to run upon the rails of a railway having rollers thereon, a frame movable transversely upon said carriage, com prising transverse bars resting upon said rollers, cutters upon the ends of said frame, adapted to groove a sleeper beneath it upon the road-bed means for driving said cutters and means for adjusting the height of said cutter.

2. In a machine for grooving railway sleepers, the combination of a carriage adapted to run upon the rails of a railway, and a cutter adapted to groove a sleeper beneath it upon the road-bed, said cutter being adjustable to out at different inclinations and means for adjusting the height of said cutter.

3. In a machine for grooving railway sleepers, the combination of a carriage adapted to run upon the rails of a railway, cutters adapted to groove a sleeper beneath them upon the road-bed, said outters being adjustable to cut at different inclinations, and means for adjusting the height of said cutters, said means comprising screws adapted to raise and lower said cutters, a hand-wheel, transmission-shafts, a gear connection between said shafts and screws and universal joints between the ends of said shafts and said hand-wheel and said gears.

In witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.

ALBERT COLLET.
